Solving word problems requires using mathematical language to describe real-life contexts. Problem-solving strategies are often used in the natural sciences and engineering disciplines (such as physics, biology, and electrical engineering) but also in the social sciences (such as economics, sociology and political science). To solve word problems we need to write a set of equations that describes the problem mathematically.
Examples of real-world problem solving applications are:
- modelling population growth;
- modelling effects of air pollution;
- modelling effects of global warming;
- computer games;
- in the sciences, to understand how the natural world works;
- simulators that are used to train people in certain jobs, such as pilots, doctors and soldiers;
- in medicine, to track the progress of a disease.
